Phys.org / Acceptor molecule upconverts low-energy green light to high-energy purple with high efficiency
Solar cells and photocatalysts can be surprisingly inefficient. Despite light consisting of many wavelengths, the range that even highly efficient devices use is limited. Other wavelengths, especially long wavelengths, simply ...
Medical Xpress / Stem cell scientists engineer 'synthetic organizer' cells to improve kidney organoids
In a study published in Science, USC researchers paired a biological discovery with an engineering feat to create more faithful, reproducible lab-grown kidney structures from stem cells, known as organoids.
Medical Xpress / Ultra-small magnetoelectric antenna could unlock new generation of implantable devices
A breakthrough in biomedical engineering could help pave the way for tiny implantable devices capable of diagnosing, monitoring and treating a wide range of health conditions. An international team of researchers led by the ...
Medical Xpress / Dynamic protein behavior drives blood-brain barrier specialization, study reveals
A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC), in collaboration with the Proteomics Platform of the Institute for Research in Biomedicine (IRB Barcelona), has uncovered a key mechanism ...
Medical Xpress / Parkinson's patients undergoing deep brain stimulation show little to no cortical Lewy pathology
Researchers at the Icahn School of Medicine at Mount Sinai have found that patients with Parkinson's disease undergoing deep brain stimulation (DBS) show little to no Lewy pathology in the prefrontal cortex at the time of ...
Medical Xpress / Forcing cancer cells to die can alert the immune system to enhance anti-tumor attack
Unlike accidental cell death, some cells can actively decide to die through a controlled process. This is called programmed cell death and can occur in different forms, including apoptosis and necroptosis. Cells use this ...
Medical Xpress / Experts offer advice on performing endurance events in excessive heat
As pro cycling teams have been preparing for the start of the Tour de France on Saturday, extreme heat has rolled across Western Europe, smashing temperature records, cracking infrastructure and taking a toll on the population.
Phys.org / Ancient gum disease may have helped reshape jaws before human brains expanded
Human evolution is generally explained through changes in brain size, locomotion or tool use, but new research from Wits University suggests that gum disease and changes in facial structure may have been important factors ...
Phys.org / How much do friends influence teens' mental health? What a new study can (and can't) tell us
During adolescence, young people become especially sensitive to peer influence—more so than at any other time in life. So how does this affect their mental health?
Phys.org / Cosmic dust could play key role in cracking long-standing mystery of solar corona heating
A researcher at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a new study in The Astrophysical Journal suggesting that tiny charged dust grains near the sun may significantly ...
Phys.org / NASA's Hubble spots star-spangled cosmic scene
More than 500,000 stars blaze red, white, and blue in this image from NASA's Hubble Space Telescope, released in celebration of the United States' 250th anniversary. The image showcases Messier 3 (M3), one of the Milky Way ...
Tech Xplore / Electric car analysis reveals moral case for accelerating green transition
Recently, it has been argued that a rapid transition is unjust—particularly because of concerns about mining critical minerals, including for EVs. Specific concerns have been raised about deaths among artisanal and small-scale ...
